本番環境のManagement APIアクセストークンの取得

本番環境に定期的かつ頻繁な呼び出しを行うには、バックエンドでトークンを自動的に提供するプロセスを構築（して、擬似的に無期限のトークンに）します。

前提条件

マシンツーマシンアプリケーションを登録する

アクセストークンの取得

Auth0にManagement API v2トークンを求めるには、前提条件のステップで作成したM2Mアプリケーションの資格情報を使用して、POST操作をhttps://{yourDomain}/oauth/tokenエンドポイントに実行します。

ペイロードは次の形式でなければなりません。

cURL
C#
Go
Java
Node.JS
Obj-C
...

curl --request POST \
  --url 'https://{yourDomain}/oauth/token' \
  --header 'content-type: application/x-www-form-urlencoded' \
  --data grant_type=client_credentials \
  --data 'client_id={yourClientId}' \
  --data 'client_secret={yourClientSecret}' \
  --data 'audience=https://{yourDomain}/api/v2/'

アプリケーションの設定タブで必ず`{yourClientSecret}`をクライアントシークレットに更新します。

要求パラメーター：

要求パラメーター	説明
grant_type	実行したいOAuth 2.0フローを示します。マシンツーマシン通信については、`client_credentials`の値を使用します。
client_id	これは作成したマシンツーマシンアプリケーションのクライアントID フィールドの値です。アプリケーションの設定タブで見つけることができます。
client_secret	これは作成したマシンツーマシンアプリケーションのクライアントシークレットフィールドの値です。アプリケーションの設定タブで見つけることができます。
audience	これは`Auth0 Management API`の識別子フィールドの値です。APIの設定タブで見つけることができます。

update:client_grantsスコープとcreate:client_grantsスコープは、クライアントがそれ自体にさらなる権限を付与できるようにするため、高い権限を持つアプリケーションでのみ使用してください。

応答には署名済みJWT、有効期限、付与されたスコープ、およびトークンタイプが含まれます。

{
  "access_token": "eyJ...Ggg",
  "expires_in": 86400,
  "scope": "read:clients create:clients read:client_keys",

上記から、アクセストークンの期限が24時間（86400秒）後に切れること、アプリケーションの読み取りと作成が許可されていること、そしてベアラーアクセストークンであることがわかります。

Auth0のNode.jsクライアントライブラリーの使用

HTTP呼び出しの代わりに、node-auth0ライブラリーを使用して自動的にManagement APIのトークンを取得することもできます。

アクセストークンの使用

このトークンを使用するには、要求のAuthorizationヘッダーに含めます。
